"Danganronpa" by Nanami ChiaKi

Chiaki Nanami is a character from the Japanese game Super Danganronpa 2: Sareyo Zetsubou Gakuen and its spin-offs. She is a super high-level gamer, voiced by Kana Hanazawa. She is a mute girl with pink hair and pink eyes, usually wearing a black cat hoodie and carrying a cat backpack. She often sleeps deprived from staying up all night playing games, and frequently yawns during the day. She is an all-around gamer except for romance, with extraordinary concentration, able to introduce herself while playing and entering "Strategy God Mode." She is shy by nature, finds it hard to speak without organizing her words beforehand, and puts on a hat when she's shy or thinking. Chiaki Nanami is actually a student observer sent by the Future Organization to the New World program. She is an artificial intelligence, created by Chihiro Fujisaki, and her brother is Alter Ego. She has always helped Hajime Hinata and others fight against the dark side. In Komaeda's "Find the Traitor" incident, she actively had Hajime identify herself as a "spy" to keep everyone alive, and was later executed by Monokuma. In the ending of Danganronpa 3 - The End of Nozomimine Academy, she appears as a phantom.
